ABSTRACT OF THE DISCLOSURE A digital, abridged spectrophotometer with a detecting head having a housing with a viewing port and a light source. At least five photo-responsive devices, which in one embodiment may be filtered photo-diodes, are mounted in the head for each receiving light from a sample or standard in the viewing port. A standard sheet of Vitrolite* is mounted on the housing for movement with a plunger, which trips a switch, to cover the viewing port, while a standard black sheet can be pivoted to cover the viewing port for the calibration which precedes each reading. A digital computer calculates the values from the signals produced by the photo-diodes and provides signals for a display of the color values. The computer has a memory in which signals corresponding to standardized reflectance values of at least one standard sample in different wavelength ranges are stored, a first processing circuit which compare the signals corresponding to the standardized reflectance values to signals corresponding to the reflectance values of the standard sample provided in the port, and which stores correction signals corres- ponding to the result of the comparison, and a second processing circuit which after the exchange of the standard sample by the sample to be measured converts the non-corrected signals corres- ponding to the reflectance values of the sample to be measured by means of the correction signals to corrected signals corres- ponding to the reflectance values of the sample to be measured.
